Between A Rock And...: Non-Binary Gender in Atheism

When women started talking about women's issues in the skeptic and atheist movements, it created an incredibly charged atmosphere within those communities. A couple years later, we're still having this heated discussion. In talking about gender-related issues, how well do people within the community address trans* people, particularly non-binary-identified individuals? Is there an overlap between misogynistic attitudes and transphobic attitudes? Is non-binary erasure a problem for the atheist/skeptic communities? What place do binary and non-binary trans* people have within the community, and what are their contributions?
